Bumping an old thread

I found out today the XT 660 X I bougt is missing the lower tensioner. To be specific the whole metal part where it bolts onto snapped off. It did not have raised links by the way.

So have to figure out how to reconstruct a new tensioner and figured the easiest would be to just recreate the original and perhaps strengthen the base a bit. All I have to go by are the photo's here and it will get me a long way I think. Just wondering whether about a few more dimensions as the metal assembly is bent. Can anyone provide the red A (talking about the top line, sides should be 56 mm) and green B as shown in the picture? Thanks in advance!!!



I was thinking of attaching this pully from ebay. It has the same dimensions as the top tensioner and the added advantage of bearings + obviously costs f*** all
